Not sure what you mean by “a bit damaged.” Maybe something was lost in the translation, but the best time to back up a boot drive is before it is a bit damaged. Another consideration is how much is on the boot drive.
Maybe this post will help.
Hello, thanks for your answer, I hope the google translator helps me !!.
-The SD card is physically damaged and I am afraid that one day the operating system will not start.
-SD card has only the boot system and configuration (not for saving data or files)
-on the CPU that has a 6TB hard disk where I have very important work items and files with which I work
-What I want is to clone what I have in SD and transfer it to a pendrive.
-This way I will not use the SD anymore to start, I will do it from the pendrive
